Class WsContextListener

java.lang.Object

org.apache.tomcat.websocket.server.WsContextListener

All Implemented Interfaces:

java.util.EventListener, ServletContextListener

public class WsContextListener
extends java.lang.Object
implements ServletContextListener

In normal usage, this ServletContextListener does not need to be explicitly configured as the WsSci performs all the necessary bootstrap and installs this listener in the ServletContext. If the WsSci is disabled, this listener must be added manually to every ServletContext that uses WebSocket to bootstrap the WsServerContainer correctly.
